Decimal minutes
Every once in a while I follow a surveyor that sometimes used degrees, minutes, decimal minutes instead of the usual degrees, minutes, seconds. His plats are the only ones I ever recall using that format. The inexperienced crew chief could get burned by mistakenly trying to use the decimal minutes as seconds. The first time I encountered that format, I wasn’t sure about my interpretation until I tried closing the plat. Probably took half an hour since I had to convert every course to ddmmss. I couldn’t figure out how to get the hp48 data collector to accept the ddmm.m format. Was that format common in other areas?
